Question

1. the area of a rectangular playground is 78 square meters. if the length of the playground is 13 meters, what is its width?

Explanation:

Step1: Recall the formula for the area of a rectangle

The area \( A \) of a rectangle is given by the formula \( A = l \times w \), where \( l \) is the length and \( w \) is the width. We need to solve for \( w \), so we can rearrange the formula to \( w=\frac{A}{l} \).

Step2: Substitute the given values into the formula

We know that the area \( A = 78 \) square meters and the length \( l = 13 \) meters. Substituting these values into the formula \( w=\frac{A}{l} \), we get \( w=\frac{78}{13} \).

Step3: Perform the division

Calculating \( \frac{78}{13} \), we find that \( 78\div13 = 6 \).

Answer:

The width of the rectangular playground is 6 meters.
